Q: 19.8Vx2.02A= ~40W MAX --> Full sunshine!!

kajzer123 dzięki że napisałeś bo potrzebuje taki mały do plecaka i 40w mi wystarczy żeby tel doładować, a swoją drogą w zeszłym roku kupiłem panele DOKIO 150W i powiem ci że na pełnym słońcu wyszło mi pod 200w więc więcej niż deklarowana...

lunatictr For 50W version, 23.6V is the open circuit voltage. That is when there is no power pulled from the panel. 2.2A is the short circuit current., they is the current you get when you connect + and - of the panel output directly to each other. You don't get the power by multiplying them. You have to multiply the Vmp (Voltage at maximum power, here 19V.) and current at that voltage (2A). Calculating from the size and the low efficiency of the pet type of panels (12-14%) this may not be even 38Ws. Maybe 30W. If the efficiency is 18%, you may get 38W.

Teotiltil when a photovoltaic is working the max actual power is calculated at the max voltage that can produce max amperage. And all of this at 1000cd per m2 irritation. for example this photovoltaic can not exceed 60-65w. i would be actual super happy if i could see around 50w in real conditions. i can predict that in normal conditions would produce about 15v X 2.5A 30-35w max.... Open voltages are useless except to prevent some electronics burning. when the photovoltaic is work the voltage drops significantly.

Wyre if you are using locking nuts is not really a problem. tighten them down nicely and I've never had a prop loosen a nut. it can happen though, I've heard of it happening to other period but I've never experienced it.
